For the time being you should create it by yourself by exporting it from a trusted full node doing this:
tezos-node snapshot export --block BLOCK_HASH FILE.full

This paragraph is interesting and talks about ...
There is no indicator on the blockchain or the node to know if the chain is at latest or "bootstrapped". That's how blockchains work. At any moment there could be a new block or a new fork of the chain. The only way for your node to know if your local stored version of the blockchain is the source of truth is by asking other node peers on the network. As you ...
Alphanet size is currently around 13 GB. It is a very IO intensive process and it is recommended you use SSD where it it should take less than 4 hours to complete.
There isn't a commonly used quicksync for alphanet, but mainnet quicksync files can be found here https://www.tzdutch.com/quicksync/
The KT address is derived from the signed operations bytes that originated the account. To calculate it you will need to first hash the operations bytes with blake2b (32 bytes). Then you prepend an index of 4 bytes that starts at 0 ([0, 0, 0, 0]) and is incremented by one for every additional origination (in case it's a batch of multiple originations). Then ...
Can you open an issue on https://gitlab.com/tezos/tezos/issues/ ?
And a few details such as :
is your script up to date ?
did you bootstrapped your node from nothing ? Or used a storage snashpot ?
are you running your node in Full or Rolling (or don't know) mode ?
TzDutch provide snapshots via their QuickSync service - https://www.tzdutch.com/quicksync/
